Due to the use of macros and longlong.h, we use variables which are
only used by some architectures. At least gcc 4.7.2 prints new
warnings about set but not used variables. This patch silences them.
mpi-internal.h, mpi-scan.c: Edit all preprocessor instructions to remove
whitespace before the '#'. This is not required by C89, but there are
some compilers out there that don't like it.
